FRED HUME, OF ST. LOUIS, MISSOURI, ASSIGNOR TO INTERNATIONAL SHOECOMPANY,

OF ST. LOUIS, MISSOURI, A CORPORATION OF DELAWAR MACHINE FOR USE IN THE MANUFACTURE OF SHOES.

Application filed November 30, 1925. Serial No 72.140.

This invention relates to machines for use in the manufacture of shoes.

An object of the invention is to provide a machine by use of which the work of forming and shaping the toes of shoes is greatly expedited, and the cost of manufacture correspondingly reduced by providing devices for pressing the edge of the upper upon the edge of the sole and shaping the upper properly for In attachment to the sole.

Another object of the invention is to provide a machine having presser and shaping devices, in combination with means for pressing said devices upon the shoe parts to be affected thereby and at the same time automatically actuating said devices to shape the adjacent portions of the uppers of the shoes and to secure them to the sole.

Another object of the invention is to provide a machine embodying the mechanisms mentioned,in combination with heating means for heating said pressing and shaping devices to adhesively attach the upper to the sole.

Other objects will appear from the following description, reference being made to the accompanying drawings, in which Fig. 1 is a front elevation of the machine embodying my invention.

Fig. 2 is a side elevation.

Fig. 3 is a diagrammatic view of the heatin device.

ig. 4. is an enlarged plan view of'the pressing and shaping devices.

Fig. 5 is a front elevation thereof.

Fig. 6 is a sectional view on the line 6-6 of Fig. 4-.

Fig. 7 is a sectional view showing the means for supporting the movable jaws.

Theoperative mechanism of the machine is supported by an appropriate frame comprising standards 1 strengthened by cross connec tions 2, 3 and 4 and supporting a top plate or table 5.

The specific embodiment of the invention shown comprises units, each of which is constructed and arranged to operate upon the toes of a pair of shoes. The invention may be varied in this respect and the operating mechanism may be constructed and designed to operate upon the heel seats or other parts of the shoes and to perform the entire shaping of said heel seats or other parts and to effect ad hesive attachment of the same to the sole.

Each unit of the machine includes shaft 6 mounted for vertical reciprocation through a bearing 7. The shafts 6 of the respective units may be independently operative as shown. The operating devices for each shaft include a lever 8 extending through a slot 9 in the corresponding shaft 6 and having its front end pivoted to the cross connection 3 and its rear end connected by a link 10 with a treadle lever 11. By downward pressure upon the treadle lever 11 the corresponding shaft 6 will be moved downwardly in opposition to a raising and supporting spring 12 connected to the lever 8 by a link 13. Thus it will be seen that the springs 12 raise the respective shafts 6 to and normally support them in their upper or starting positions, and that the t-readles 11 are operative to lower the shafts 6 inppposition to the springs 12. Each of the shafts 6 may be held in its down position in opposition to its spring 12 by a device provided for that purpose. Asshown each treadle lever 11 has a lateral projection 14.- designed and adapted to engage with the teeth of a ratchet 15 when the lever 11 is down. This is for the purpose of holding the presser and shaping devices pressed upon the shoes until the purpose of such operation has been completed.

The front or working side edge of the table top 5 has a number of serrated plates 16 attached thereto. The under side of the toe extremities of the soles are placed upon the plates 16 when the uppers are to be pressed to shape and attached to the soles. The serrations on the plates 16 prevent the sole from slipping. Each of the shafts 6 supports one or more presserand shaping devices and, in the embodiment of the invention shown, each shaft 6 supports a pair of such presser and shaping devices.

A plate 17 is detachably secured to the upper end of each shaft 6 above the table top 5 and is movable with the shaft to which it is attached. The plates 17 are guided vertically and held from lateral oscillation by rods 18 extending upwardly from the table top 5 hassurn into holes 19 in the plate 17. Cams 20 are rigid with the rods 18 and face the sides and the inner ends of the plates 16. Pressing and shaping devices are supported by the plates 17, one or more of such devices being provided for each of the plates 16. The plates 17 have recesses 21 to receive the toes of shoes for shaping the toe portion of the uppers during operation of the machine.

' two wipers of each pair being connected by pivots 24 at their inner ends permitting converging and spreading movements of the outer ends of thewipers. The wi ers 23 have beveled inner edges 25, the bevele upper surfaces flaring upwardly and outwardly forming attenuated lower edges. When the shaft 6 is moved down by operation of its treadle 11 the inner end and the side edges of the wipers 23 0perate against the cams 20 with the result that the cam 20 at the inner end pushes the wipers outwardly and the cams 20 at the sides push the wipers toward each other. This causes the edges 25 of the wipers to press the toe portion of the upper inwardly under and around the former, or last, and the edge portion of the upper upon the'sole. Glue having been applied between the up er and the sole, the upper will be properly s iaped and secured to the sole. 7

The machine may include heating devices to heat the shaper and presser. As shown conventionally an electric heater 26 is in connection with each of the plates 17. .This heater is preferably a multlple stage resistance'he'ater and is controlled by a multiple point switch 27 in order to obtain the different degrees of heat required for difi'erent purposes. Thus the sha-per or presser may be heated to different degrees in conformity with the requirements of the operations. The resistance circuit is energized by leads 28 and 29, and there is interposed in the circuit a light circuit controlling the light 30 indicating when the circuit is open or closed, it being understood that the lamp is lighted when the circuit is closed.

The wipers 23 are-removable and interchangeable, and wipers for operating on shoes of different sizes may readily be mounted in the machine.v

This machinegreatly facilitates and expedites the work for which it is intended, and by use of the machine one operator can perform a great deal more work than has been possible by use of other machines now in general use.

The construction of the machine and the an rangement of the parts thereof may be varied within equivalent limits without departure from the nature and principle of the invention as set forth in the appended claims.
